Yup. I've got one of her brothers in a pen over some Buckeyes right now. I'm hoping I find out he's homozygous. I've also got one pullet that's not quite as nice as this one, but pretty good, and I'm thinking she's homozygous on leg color.
My original plan for this year was to color test the males for leg color first and then a few of my best females and get to homozygous leg color. But now I'm seeing females like this one that I'm pretty sure are hetero and I've got a pretty nice BW cockerel with clean hackles and the lighter color of hackles, saddle, and better wing bay and bows that I think is hetero too. So now I'm thinking I may go ahead and breed some of these hetero birds and just select out for the darkest leg color and cull any yellow or willow and hopefully all the hetero that I get too.
The two pullets I took to the show, I'm pretty sure, are hetero and they did fine. If you look at the pic of the Wheaten you can see she's a little light on leg color.
